Whether or not large areas of whitening on both sides of the vulva will go away on their own depends on the cause of the disease, and may or may not go away on their own. If the whitening of the vulva is caused by vulvar leukoplakia or vitiligo, it usually does not go away and may get worse over time. Vulvar leukoplakia can be treated with prednisone, dexamethasone, and hormonal medications as prescribed by your doctor. Vitiligo can be treated with tacrolimus, pimecrolimus, and other medications as prescribed by the doctor. If it is because of the vaginal infection mold caused by pseudomycosis, resulting in the whitening of the leukorrhea attached to the vulva, the treatment of vaginitis can be disappeared. Normally, you need to do a good job of cleaning the vulva and keep the vulvar skin dry.
